Abstract
A dry transfer decal includes a flexible carrier layer as a substrate with a high adhesion characteristic urethane layer on the substrate. Ink layers are printed on the urethane layer and a high tack adhesive is screened over the printed ink layers. The decal may be transferred from the substrate to a surface by applying a local pressure through the substrate on the decal thereby impinging the decal onto the surface. Specific formulations for the urethane layer and the various ink layers are disclosed.
Claims6
A dry transfer decal comprising, in combination:
- a flexible carrier layer as a substrate;
- a high adhesion characteristic lacquer printed in a desired pattern as a first layer on the carrier layer, the high adhesion characteristic lacquer comprising the following mixture:
- (a) 10-25% by weight of a solvent soluble flexible urethane resin;
- (b) 0-2% by weight nitrocellulose;
- (c) 0-5% by weight of a plasticiser;
- (d) 30-60% by weight of a solvent, said mixture having extensibility as a dry film of between 50 and 500%;
- at least one subsequent printed pattern layer on the first layer;
- and
- a high tack adhesive layer on said printed pattern layer, said high tack adhesive comprising the following mixture:
- (a) 10-30% by weight high molecular weight polyvinyl ether;
- (b) 5-20% by weight tackifying resins;
- (c) 5-20% by weight plasticising resin;
- (d) 20-30% by weight solvent;
- and
- (e) 2-8% by weight highly dispersed silica,
- said high adhesion characteristic lacquer defining means to retain the printed layer and the high tack adhesive layer on the substrate until the high tack adhesive layer is subjected to localize release pressure, said high adhesion characteristic lacquer having flexibility greater than that of the flexible carrier substrate.
