ABSTRACT:
Photographs and other indicia-bearing opaque sheets of paper are laminated to molded articles by:
(a) positioning the opaque sheet of paper betweeen two flexible sheets of uncured catalyst-containing thermosetting melamine-formaldehyde condensation product, to form a layup;
(b) applying the layup to a surface of a shaped three-dimensional article formed of a partially cured catalyst-containing thermosetting melamine-formaldehyde molding resin, with the indicia-bearing surface of the opaque sheet facing away from said article; and
(c) applying heat and pressure to the assembly to cure the condensation product and complete the cure of the partially cured resin.
