A process for creating a stable 3D pattern on a non-fibrous substrate comprises depositing a heat-expandable composition on the substrate; causing the disposed composition to expand in volume, thereby forming a 3D pattern having a perimeter; causing the composition to solidify; and applying a varnish coating over the pattern's perimeter and an area of the substrate adjacent thereto such that the varnish covers a sealing region extending at least 0.5 mm from the perimeter on both sides thereof. An article of manufacture comprises a non-fibrous outer surface having a 3D decorative pattern applied thereto and coated with a varnish coating covering a sealing region extending at least 0.5 mm from the pattern's perimeter on both sides thereof.

In a decorative sheet including a surface layer and an adhesion layer, the surface layer is a polyurethane layer obtained by crosslinking using a curing agent and coating and drying of a straight chain polyurethane resin having a specified molecular weight and acid value, the polyurethane resin being obtained by reaction of a diamine chain extender agent with a polyurethane prepolymer obtained by reaction of a polycarbonate diol having an alicyclic structure, an aliphatic diol having a carboxyl group, and 4,4-cyclohexylmethandiisocyanate.

The present invention relates to a thermoplastic laminate for an eyewear, a decorative part comprising the thermoplastic laminate and a preparation process therefor. In particular, during the preparation of the laminate, a high frequency welding machine is used for bonding thermoplastic layers. The present invention uses a high frequency welding machine for the instant welding of the thermoplastic layers. Good bonding strength exists between different layers. Further, the patterns of the core layer are intact, and have high-definition images. The patterns are located in the core layer, not affected by external environmental factors, and not easily abraded. Further, multiple surfaces of the part for an eyewear have patterns, increasing the beautiful appearance of the part for an eyewear, and meeting the requirements of customers to the largest extent.

Aspects of this disclosure relate generally to relief sculptures, and more particularly to methods of creating relief sculptures, kits for creating relief sculptures, and the relief sculptures themselves. A method may include, for example, contacting a transparent plate and a first surface of a pliable sheet, the first surface of the pliable sheet comprising an image, wherein at least a portion of the image is visible through the transparent plate, applying a sculpting medium to a portion of the transparent plate that corresponds to an image feature visible through the transparent plate, and adhering a second surface of the pliable sheet to the transparent plate, the sculpting medium, or both, such that the image feature corresponds to the sculpting medium.
