专利汇可以提供Coating compositions and processes专利检索，专利查询，专利分析的服务。并且A carboxylic acid chloride or bromide, a sulfonyl chloride or bromide, cyanuric chloride, calcium hypochlorite or phosphorus oxychloride and optionally a buffering pigment are combined with a liquid, acrylate ester resin curable by exposure to high-energy ionizing radiation to yield a coating composition which upon being cured in air by exposure to ionizing radiation yields a coating having an essentially tack-free surface.，下面是Coating compositions and processes专利的具体信息内容。
2. The composition of claim 1 wherein the amount of cyanuric chloride is from 1 to 5 percent by weight.
3. The composition of claim 1 wherein said resin is produced (1) by reacting a 2-hydroxyalkyl acrylate or 2-hydroxyalkyl methacrylate with a polyfunctional material selected from the group consisting of (a) dicarboxylic acids and dicarboxylic acid chlorides having from four to 15 carbon atoms, and (b) polyfunctional isocyanates having terminal, reactive isocyanate groups; or (2) by reacting a half-ester of a 2-hydroxyalkyl acrylate or 2-hydroxyalkyl methacrylate and a dibasic acid with a polyepoxide.
4. The composition of claim 3 wherein the amount of cyanuric chloride is from 1 to 5 percent by weight.
5. In a method of coating a surface of a substrate comprising (1) applying on said surface a liquid coating composition comprising a liquid, acrylate ester resin which is curable by exposure to ionizing radiation and which, when so curing, is susceptible to inhibition of surface curing by atmospheric oxygen; and (2) curing the resulting liquid coating in the presence of atmospheric oxygen by exposing said coating to ionizing radiation; the improvement wherein said coating composition further comprises from 0.1 to 10 percent by weight of an acidic halide soluble in or dispersible in said resin, said acidic halide being selected from the group consisting of (a) compounds of the formula where R is an aliphatic or aromatic group and X is Cl or Br; and (b) cyanuric chloride, calcium hypochlorite and phosphorus oxychloride, whereby the susceptibility of said composition to said inhibition is reduced or eliminated.
6. The method of claim 5 wherein curing of said liquid coating is effected by exposure thereof to high-energy electrons.
7. The method of claim 6 wherein said acidic halide is selected from the group consisting of adipoyl chloride, lauroyl chloride, terephthaloyl chloride, isophthaloyl chloride, cyanuric chloride, calcium hypochlorite and phosphorus oxychloride.
8. The method of claim 6 wherein said acidic halide is selected from the group consisting of cyanuric chloride, isophthaloyl chloride, calcium hypochlorite and phosphorus oxychloride.
9. The method of claim 6 wherein said acidic halide is cyanuric chloride.
10. The method of claim 6 wherein the amount of said acidic halide is from 1 to 5 percent by weight.
11. The method of claim 6 wherein said substrate is wood.
12. The method of claim 11 wherein said acidic halide is cyanuric chloride.
13. The method of claim 6 wherein said resin is produced (1) by reacting a 2-hydroxyalkyl acrylate or 2-hydroxyalkyl methacrylate with a polyfunctional material selected from the group consisting of (a) dicarboxylic acids and dicarboxylic acid chlorides having from four to 15 carbon atoms, and (b) polyfunctional isocyanates having terminal, reactive isocyanate groups; or (2) by reacting a half-ester of a 2-hydroxyalkyl acrylate or 2-hydroxyalkyl methacrylate and a dibasic acid with a polyepoxide.
14. The method of claim 13 wherein said acidic halide is cyanuric chloride.
15. The method of claim 14 wherein said substrate is wood.
16. In a method of coating a surface of a substrate comprising (1) applying on said surface a liquid coating composition comprising a liquid, acrylate ester resin which is curable by exposure to ionizing radiation and which, when so curing, is susceptible to inhibition of surface curing by atmospheric oxygen; and (2) curing the resulting liquid coating in the presence of atmospheric oxygen by exposing said coating to ionizing radiation; the improvement wherein said coating composition further comprises from 0.1 to 10 percent by weight of 2-naphthalenesulfonyl chloride, whereby the susceptibility of said composition to said inhibition is reduced or eliminated.
17. The method of claim 16 wherein curing of said liquid coating is effected by exposure thereof to high-energy electrons.
