Abstract
The present invention relates to the use for coating three-dimensionally structured surfaces and/or moldings of melamine resin sheets and/or films produced from cellulosic fiber materials post- or pre- and post-impregnated with an aqueous solution comprising (i) a melamine-formaldehyde condensate, (ii) an etherified melamine-formaldehyde condensate, and (iii) a polymer dispersion.
Claims20
An article comprising three-dimensionally structured surfaces and/or moldings (3D coating) and a coating thereon of melamine resin sheets and/or films produced from cellulosic fiber materials post- or pre- and post-impregnated with an aqueous solution comprising
- (i) a melamine-formaldehyde condensate,
- (ii) an etherified melamine-formaldehyde condensate, and
- (iii) a polymer dispersion.
A synthetic resin mixture for impregnating cellulosic fiber materials, comprising
- (i) from 5 to 50% by weight of a melamine-formaldehyde condensation product,
- (ii) from 5 to 50% by weight of an etherified melamine-formaldehyde condensation product, and
- (iii) from 40 to 90% by weight of a copolymer in aqueous dispersion form which is crosslinkable by condensation reaction,
- the amounts of components (i), (ii) and (iii) adding up to 100% by weight and being based on the liquid resin mixture
