A STABLE OIL-IN-WATER EMULSION ADHESIVE WHICH WILL PRODUCE A TACKY, PRESSURE-SENSITIVE ADHESIVE COATING UPON A SURFACE TO WHICH IT HAS BEEN APPLIED WHEN IT IS ALLOWED TO REMAIN ON THE SURFACE FOR A PERIOD OF TIME SUFFICIENT TO PERMIT EVAPORATION OF A SUBSTANTIAL PORTION OF THE VOLATILE COMPONENTS THEREOF WHICH COMPRISES (1) AN OIL PHASE OF DISPERSED DISCRETE PARTICLES, EACH PARTICLE COMPRISING AN ADHESIVE MASS CONTAINING A RUBBERY, CONJUGATED DOILEFIN POLYMER AND A TACKIFYING RESIN MXED WITH AN ORGANIIC LIQUID HAIVNG A BOILING POINT BETWEEN 115* AND 275*F. WHICH IS CAPABLE OF DISPERSING SaID POLYMER AND SAID TACKIFYING RESIN TO FORM A LIQUID DISPERSION THEREOF, (2) A WATER PHASE AND AN (3) INTERPHASE CONSISTING ESSENTIALLY OF AN EMULSIFYING AGENT, SAID AGENT BEING CAPABLE IN AND OF INSTALLING FLOOR-COVERING TILES ON A
Claim 2
Dependent Claim
