Powder composition of crystalline polyester containing terminal methacryly group

摘要

The present invention relates to a radiation-curable composition for use as a varnish or paint comprising a crystalline polyester containing a terminal carboxyl group and a crystalline polyester containing at least one terminal methacrylate group comprising a reactive product of a glycidyl methacrylate The crystalline polyester containing the terminal carboxyl groups is a) (a) (a) (a. 1.1.) 85 to 100 mol% of terephthalic acid or 1,4-cyclohexane Dicarboxylic acids and (a, 1.2) acidic compositions containing from 0 to 15 mol% of one or more other aliphatic, cycloaliphatic or aromatic di- or polycarboxylic acids having from 4 to 14 carbon atoms and (2) (a, 2,1) 85 to 100 mol% of a saturated, linear aliphatic diol having 2 to 12 carbon atoms and (a.2.2) 0 to 15 mol% of one or more other fats Or b) (b.1.1) 85 to 100 mol% of a saturated, linear aliphatic dicarboxylic acid having 4 to 14 carbon atoms, or a linear or branched aliphatic dicarboxylic acid having 4 to 14 carbon atoms And (b. 1.2) an acid component containing from 0 to 15 mol% of one or more other aliphatic, cycloaliphatic or aromatic di- or polycarboxylic acids having from 4 to 14 carbon atoms, and (b) From 85 to 100 mol% of 1,4-cyclohexanediol, 1,4-cyclohexanedimethanol or ethylene glycol and (b.2.2) from 0 to 15 mol% of one or more other aliphatic or cycloaliphatic groups having from 2 to 15 carbon atoms A polyester which is a product of an alcohol component containing an aliphatic di- or polyol.
