Abstract
Abstract A WATER RELEASABLE DECALCOMANIA PAPER INCLUDES A BASE MEMBER SUPPORTING SEVERAL LAYERS, E.G., A NON-POROUS BARRIER LAYER, A NON-BLOCKING ADHESIVE FILM TOP COATING AND THE DECALCOMANIA PRINTING OR LACQUER. THE NON-POROUS BARRIER LAYER, CONTAINING INDIVIDUAL PARTICLES OF STARCH AND A DISCONTINUOUS POLYMER PHASE PREVENTING CONTACT BETWEEN AT LEAST SOME OF THE STARCH PARTICLES, PREVENTS PASSAGE OF WATER INTO THE BASE DURING APPLICATION OF THE TOP COATING, THE LATTER FORMING THE ADHESIVE FOR THE DECALCOMANIA PRINTING AND MADE UP PRIMARILY OF DEXTRIN. A POLYVINYL ALCOHOL OR METHYL CELLULOSE LAYER MAY BE DEPOSITED ON THE DEXTRIN, THE DEXTRIN BEING MECHANICALLY OR CHEMICALLY BROKEN. THE DECALCOMANIA PAPER MAY BE OF THE SIMPLEX OR DUPLEX TYPE AND MAY BE OF THE "FACE-DOWN" OR "SLIDE-OFF" VARIETY.
