摘要

THE INVENTION IS ABOUT A PROCESS FOR THE PRODUCTION OF MULTILAYER COATINGS, FOR WHICH A WATER BASED PIGMENTED COATING COMPOUND CONTAINING A WATER SOLUBLE EMULSION POLYMER IS USED. WATER SOLUBLE EMULSION POLYMER IS PRODUCED THROUGH THE POLYMERIZATION OF A TWO-STAGE EMULSION. IN THE FIRST, A MONOMER MIX WHICH, WHETHER POLYMERIZING BY ITSELF, WOULD GIVE PLACE TO A POLYMER WITH A TRANSITION TEMPERATURE (TG2) OF -60 TO 20 C, IT POLYMERIZES IN THE PRESENCE OF THE POLYMER PRODUCED IN THE FIRST STAGE. THE HIDROXYL NUMBER OF THE EMULSION POLYMER RANGES BETWEEN 2 AND 100.
