摘要:
A thermosetting transparent coating material, its preparation and use. The coating includes (meth)acrylate (co)polymer having a number-average molecular weight of from 1,000 to 6,000 daltons, a glass transition temperature of −15 to +70° C., and a hydroxyl number of from 80 to 200 mg KOH/g; polyester having a number-average molecular weight of from 800 to 6,000 daltons, a hydroxyl number of from 80 to 200 mg KOH/g and an acid number of from 1 to 50 mg KOH/g, comprising, based on the polyester, from 30 to 70% by weight of cycloaliphatic structural units; a blocked polyisocyanate in which the blocked polyisocyanate groups are attached to flexibilizing structural units which, as part of a three-dimensional network, lower its glass transition temperature; and blocked polyisocyanate in which the blocked polyisocyanate groups are attached to hardening structural units which, as part of a three-dimensional network, raise its glass transition temperature.
