“…Several groups have reported various water-developable materials and their applications, such as base-amplifying copolymers and positive-working photoresist, flexographic printing plates consisting of a photosensitive matrix and the diffusion of unreacted component and positive working heat-sensitive imaging composition [5][6][7][8][9][10][11][12]. In our previous work [13], we have also studied a water developable thermo-sensitive latex film. Despite many efforts directed to the development of laser-imageable printing plates, there is still a need for plates that require no organic solvent or alkaline developing solution.…”

This paper was focused on the synthesis and properties of a watersoluble resin having tertiary amine oxide side substituents. First, 3-(dimethylamino)propanoic acid was synthesized through the addition reaction of dimethylamine with methyl acrylate, followed by hydrolysis of the adduct. Then, 3-(dimethylamino)propanoic acid was oxidized with hydrogen peroxide to obtain 3-(dimethylamino)propanoic acid oxide. Finally, epoxy phenolic was reacted with 3-(dimethylamino)propanoic acid oxide to get the end product. Thermal behaviors and thermo-induced solubility change of the prepared resin were investigated. It was found that the tertiary amine oxide resin was still water soluble even after heating at 120°C for 1 h. However, it readily became completely water insoluble after heating at 170°C for a short period of time. Thin films were prepared with the aqueous solution of the tertiary amine oxide resin and an infrared (IR) dye with maximum absorption at 830 nm. The films could absorb 830 nm IR imaging radiation and give negative image after developing with neutral water. The water-soluble thermosensitive resin might be used in chemical-free thermal laser imaging applications.

“…The dye-containing polymer latexes have been widely applied in many fields, such as coating, paint, and ink industries, [1][2][3][4][5][6] which can be prepared through emulsion polymerization [7,8] or miniemulsion polymerization [5,[9][10][11][12] in the presence of oil-soluble dyes. For example, Takasu et al incorporated copper phthalocyanine and styryl dyes into polystyrene latex particles using miniemulsion polymerization.…”

A polymerizable red dye 1-(6-acrylamidohexylamino) anthraquinone (AHAQ) was synthesized and used to prepare colored polymer latexes using styrene and butyl acrylate as main monomers. Influences of the initiator and surfactant amounts, oil/aqueous phase ratio, and AHAQ content on the polymerization process, the particle size, and surface tension of the resulted latex were investigated, and the migration resistance and light fastness of the red latex films were determined. Results showed that the polymerization was carried out smoothly, and the miniemulsion polymerization mechanism was confirmed by monitoring the dimensions of oil phase before and after polymerization. The latex particle size can be adjusted by varying the surfactant amount, and when AHAQ content was 0.2-1 wt% of total monomers, the encapsulation efficiency and dye conversion could be achieved to 98.7 and 96.3%, respectively. The UV-vis spectra of AHAQ and its corresponding covalently colored polymer indicated that the maximum absorption peak was the same, meaning that the chemical structure of chromophore in AHAQ maintains unchanged after undergoing polymerization. The migration resistance and light fastness of the covalently colored latex films were much better than that of the correspondingly non-covalently colored ones.

A plasmonic composite, Ag@AgCl‐TiO2/OREC, was prepared by sol–gel combing calcination technique, precipitation, and photoreduction method. Then, Ag@AgCl‐TiO2/OREC/QCS composite microspheres were fabricated by an emulsification/chemical crosslinking method using quaternized chitosan and Ag@AgCl‐TiO2/OREC as scaffolds materials, potassium persulphate as initiator and N,N′‐methylenebisacrylamide as crosslinker. The resulting materials were characterized by Fourier transform infrared spectrometer (FTIR), X‐ray diffraction (XRD), UV‐visible diffused reflectance spectra (UV–vis DRS), and scanning electron microscopy (SEM). SEM showed that the Ag@AgCl‐TiO2/OREC/QCS composite microspheres had loose, rough surface, and spherical shape, with an average diameter of 15–45 μm. The Ag@AgCl‐TiO2/OREC/QCS composite microspheres present good adsorption–photocatalytic activities in the degradation of methylene orange (MO) and 92.1% MO was degraded after irradiation for 180 min. The high photocatalysis activity was attributed to the combined results of the relative high adsorption capacity, loose structure, and the surface plasmon resonance of silver nanoparticles formed on the surface of AgCl. © 2016 Wiley Periodicals, Inc.
