Abstract
Abstract A flocked laminate useful for number markings on baseball uniforms and appliques on children's garments, bags, etc. The laminate has a layer of an adhesive composed of a polymer emulsion and a finely divided synthetic resin admixed with the polymer emulsion, having hotmelt adhering properties, and indentical or compatible with the synthetic resin providing a base layer. The laminate exhibits outstanding adhering properties and resistance to washing when placed on an article and heat-pressed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
79 words
A flocked laminate comprising a synthetic resin base layer having hotmelt adhering properties, an adhesive layer applied to said base layer, said adhesive layer prepared from a polymer emulsion and admixed with a finely divided synthetic resin compatible or identical with said base layer synthetic resin, in an amount of about 0.1 to about 50 parts by weight per 100 parts by weight of the solids of the polymer emulsion; and a flock layer formed on the adhesive layer.
Claim 2
Dependent Claim
79 words
A flocked laminate comprising a synthetic resin base layer having hotmelt adhering properties, an adhesive layer applied to said base layer, said adhesive layer prepared from a polymer emulsion and admixed with a finely divided synthetic resin compatible or identical with said base layer synthetic resin, in an amount of about 0.1 to about 50 parts by weight per 100 parts by weight of the solids of the polymer emulsion; and a flock layer formed on the adhesive layer.
Claim 3
Dependent Claim
27 words
A flocked laminate as defined in claim 1 wherein the synthetic resin of the base layer is a vinyl resin, polyolefin resin, polyester resin or polyamide resin.
Claim 4
Dependent Claim
