This invention deals with a wrinkle coating

of any of such thinners. In preparing the var

the oil and sometimes also the ?nal composition

hardening substance is added and the mixture
to a cooking process in order to obtain a wrinkle
heated to a temperature ranging from 490° to
500° F. This temperature is held until a tough
and hard pill is obtained on a glass plate,v which
takes about from 30 minutes to one hour. The
mixture is then allowed to cool to 350° F. when
the thinner is added. In spite of the use of
oiticica oil, and in spite of the varnish being sub
jected to a cooking process, the ?nal product ob
tained is of the non-wrinkling type.
If a colored coating is to be produced, the addi
tion of a coloring paste is necessary. Such'a

longs the process of manufacture, but also in
creases the cost and requires additional care.
Moreover, the coatings prepared from the com
positions used heretofore have to be dried by
forced means such as by heating in an oven by
infra-red light or the like.

wrinkle coating compositions for the preparation
and application of which hardly any heating is
