Abstract
Abstract A method of metallizing materials by coating a substrate material with a hydrophilic composite material; electrolessly metal plating the hydrophilic composite material with a metal to render the surface conductive; followed by electroplating a metal onto the conductive surface. The method can, for example, be utilized to produce metallized foams, embossing plates for reproduction of grains and textures, and decorative coatings for substrate materials.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
125 words
A method of metallizing a substrate material comprising the steps of: (a) coating the substrate material with a hydrophilic composite material comprised of a blend of (1) at least one film forming component selected from the group consisting of vinyl chloride, vinyl acetate, and copolymers thereof; and cellulose esters and polyvinyl acetals; and (2) at least one hydrophilic component of a water soluble polymeric component, the water soluble component being dispersed throughout the coating of the composite material; (b) contacting the coated substrate with water or a water solution of salts to produce a microporous surface by dissolving the water soluble component; (c) plating the composite material with a conductive metal by electroless metal plating; and (d) electroplating a metal onto the electrolessly plated metal.
Claim 2
Independent Claim
125 words
A method of metallizing a substrate material comprising the steps of: (a) coating the substrate material with a hydrophilic composite material comprised of a blend of (1) at least one film forming component selected from the group consisting of vinyl chloride, vinyl acetate, and copolymers thereof; and cellulose esters and polyvinyl acetals; and (2) at least one hydrophilic component of a water soluble polymeric component, the water soluble component being dispersed throughout the coating of the composite material; (b) contacting the coated substrate with water or a water solution of salts to produce a microporous surface by dissolving the water soluble component; (c) plating the composite material with a conductive metal by electroless metal plating; and (d) electroplating a metal onto the electrolessly plated metal.
