Abstract
Abstract IN A DRY TRANSFER MATERIAL COMPRISING A SUPPORT, INK SIGNS AND A PRESSURE-SENSITIVE ADHESIVE LAYER COVERING BOTH THE INK SIGNS AND THE PARTS OF THE SUPPORT WITHOUT INK SIGNS, THE ADHESIVE LAYER HAS ON ITS FREE SURFACE A LAYER OF FINE SOLID PARTICLES SUCH THAT THE ADHESIVE CANNOT ACT UNLESS A SUFFICIENT PRESSURE IS APPLIED DURING A SUFFICIENT PERIOD OF TIME TO ALLOW THE ADHESIVE TO PASS THROUGH THE PARTICLE LAYER AND TO CAUSE THE INK SIGNS TO BE TRANSFERRED TO ADHERE TO A RECEPTOR SURFACE. THE INK SIGNS CONTAIN A NON-VOLATILE LIQUID MATERIAL CAPABLE OF OOZING INTO THE ADHESIVE LAYER SO AS TO REDUCE THE VISCOSITY OF THE LATTER.
