The main contribution of this paper is summarized as follow:1 Copolymer acrylate resin including hydroxyl, carboxylic and amina(-NH_2) is a new type of antifogging system and ahydrophi- lic antifogging constituents which is not found before.2 Water-soluble acrylate resin hydrophilic antifogging coating material is a new-type environmental protection material which takes ethanol as solvent and whose pastiness is adjusted by deionized water.3 The quality rate of accessory soft monomer ethyl acrylate and accessory hard monomer butyl methacrylate is 6 to 4, the quality rate of functional monomers in all monomers is 20 percent, the quality rate of MAA in the functional monomers is 22 percent, the quality rate of β-hydroxyl ethyl acrylate in the functional monomers is 8 to 10 percent and the remainder of functional monomer is acrylic acid.4 Cross-linking agent methylol acrylamide belongs to self-cross-linking system.

Two series of polyurethane acrylate grafted acrylic resins (Acr-g-TPU-PETA and Acr-gPPU-PETA) self-emulsifying systems are obtained by grafting -NCO group modified polyurethane acrylates with acrylic copolymer prepared from n-butyl acrylate, styrene,βhydroxyethyl methacrylate and acrylic acid The self-emulsifying systems showed Newtonian fluidity with viscosity closed to that of water, the solid contents were around 30% The T〓 of 15～4℃ for dried film before photocuring favored film formation at room temperature DSC and DMA results showed that PU-PETA is compatible with acrylic resin in the grafted resin The TG and dTG curves for Acr-g-PU-PETA samples were substantially different from the corresponding blends, and the brodened dTG peaks for photocured grafted resin suggest that there might be multiple interactions among chain segments The photocued film of the grafted resins self-emulsifying system exhibited good overall properties with polyurethane acrylate grafts ranging from 30% to 50%, and Acr-g-TPU-PETA series showed better properties than Acr-gPPU-PETA series The adhesion of the photocured film was 1～2 grade, impact strength was 50kg-cm and flexibility was 1mm The Shore hardness and the adhesion of the film decreased markedly if PETA was replaced by HEMA as photoactive group due to the lower C=C double bond content in the grafted resin The polyhydroxy amine-linked thioxanthones photoinitiators can be evenly dispersed in self-emulsifying system without color spot appearing in the dried film The films photocured with IV〓～I(xiàn)V〓 generally exhibited higher Shore hardness, gloss and solventresistance than that cured with Irgacure 2959 and did not induce the rusting of the iron substrate Pigmenting with titanium oxide had no effect on the photocuring The polyhydroxy amine-linked thioxanthone IV〓 and IV〓 can be new candidates for the formulation of titanium oxide pigmented photocurable water-borne coatings for their pale-yellow appearance and slight interference with the color of the coatings WB 4759 with high water-solubility coalesced and separated from the dried resin film, and even induced the rusting of iron substrate.
