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.degree. 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.
