Abstract
Abstract Decorative boards having depression patterns are obtained by applying to a patterned or colored substrate board an unsaturated polyester resin capable of being cured by irradiation of ultraviolet rays, covering a coating layer of said resin with a shading film formed of a photo-transmissible material and having thereon a shading pattern corresponding to a depression pattern to be formed in the resinous layer, irradiating the aforesaid resinous layer through the aforesaid shading film by ultraviolet rays to cure the resin in irradiated areas and peeling off the shading film. In case of decorative boards having a pattern like a face of laid bricks or tiles or stained glass where the shaded or unirradiated areas have relatively wide widths, uncured resin in the shaded areas is taken out with the shading film leaving depressions in the layer of cured resin. The resinous layer is, as it is or after application of a colorant to the depressions, cured completely to obtain a decorative board having a threedimensional pattern of a reality.

Claim 3
Dependent Claim
54 words
A method according to claim 1, wherein the coated surface is first covered by an unpatterned transparent film and then by the shading film, and said unpatterned transparent film is adhesive to the resin in its uncured state but strippable from the cured resin and wherein both films are peeled from the coated layer.
Claim 4
Dependent Claim
18 words
A method according to claim 1, wherein the base board is a plywood overlaid with a printed paper.
Claim 5
Dependent Claim
14 words
A method according to claim 1, wherein the base board is a plastic sheet.
Claim 6
Dependent Claim
23 words
A method according to claim 1, wherein the shading film is a poly(ethylene terephthalate) film having a pattern drawn with a black ink.
Claim 7
Independent Claim
141 words
A method of manufacturing depression-patterned decorative boards comprising applying an ultraviolet-curable unsaturated polyester resin to a surface of a patterned or colored base board, covering the coated surface by a shading film formed of a phototransmissible material and having thereon a shading pattern corresponding to a depression pattern to be formed in the coating layer of the said resin said film being adhesive to the resin in its uncured state but strippable from the cured resin, irradiating the coating layer by ultraviolet rays through the said shading film, peeling off the said film thereby curing the resin in the exposed areas and curing the resin in the depressions formed by the peeling-off of the said film whereby at least a portion but not all of the unexposed resin is removed with the film thereby forming depressions in the polyester surface coating.
