Abstract
Method and composition useful for improving the adhesion of flock to substrate in flocked articles are provided.
Claims24
In a method for forming a flocked article which comprises flocking an adhesive coated substrate with short fibers, wherein said adhesive is formed from a polymer selected from one of the groups consisting of
- (a) acrylic, vinyl-acrylic, vinyl, urethane and styrene-butadiene latexes,
- (b) acrylic homo and copolymers, polyesters, polyamides, polyurethanes, polyester polyols with diisocyanates, isocyanate prepolymer with polyamine, and epoxies with polyamines;
- and
- (c) diisocyanate and a polymeric polyol, epoxy resins and polyamides, epoxy resins and dimercaptans, epoxy resins and polyamines, polyenes and a peroxide, polyethylene-vinyl acetate copolymer, polyethylene-ethyl acrylate copolymer, and plasticized polyvinylchloride, the improvement comprises adding to the adhesive at least one adhesion improving additive selected from the group consisting of compounds conforming to the formulae:
- ##STR3## wherein R is a C.sub.1 through C.sub.6 alkyl or cycloalkyl radical or hydroxy group, n=0-5, inclusive and x=0-3, inclusive;
- ##STR4## wherein each R' is independently selected from hydrogen and C.sub.1 through C.sub.6 alkyl or cycloalkyl radical, R" is either hydrogen or --NR'.sub.2 wherein R' is as defined above, and Z is NO.sub.3 or XO.sub.4 wherein X is a halogen;
- and mixtures of any two or more thereof.

- wherein said adhesive is formed from a polymer selected from one of the groups consisting of
- (a) acrylic, vinyl-acrylic, vinyl, urethane and styrene-butadiene latexes,
- (b) acrylic homo and copolymers, polyesters, polyamides, polyurethanes, polyester polyols with diisocyanates, isocyanate prepolymer with polyamine, an epoxies with polyamines;
- and
- (c) diisocyanate and a poymeric polyol, epoxy resins and polyamides, epoxy resins and dimercaptans, epoxy resins and polyamines, polyenes and a peroxide, polyethylene-vinyl acetate copolymer, polyethylene-ethyl acrylate copolymer, and plasticized polyvinylchloride;
- and wherein said adhesive contains at least one adhesive improving additive selected from the group consisting of compounds conforming to the formulae:
- ##STR5## wherein R is a C.sub.1 through C.sub.6 alkyl or cycloalkyl radical or hydroxy group, n=0-5, inclusive and x=0-3, inclusive;
- ##STR6## wherein each R' is independently selected from hydrogen and C.sub.1 through C.sub.6 alkyl or cycloalkyl radical, R" is either hydrogen or --NR'.sub.2 wherein R' is as defined above, and Z is NO.sub.3 or XO.sub.4 wherein X is a halogen;
- and mixtures of any two or more thereof.
