A PROCESS FOR THE PRODUCTION OF WATER-SOLUBLE MODIFIED AMINOPLAST RESIN COMPLEX COMPRISING REACTING DICYANDIAMIDE WITH A WATER-SOLUBLE CARBOXYLIC ACID AT A TEMPERATURE IN THE RANGE OF 70* C. TO 120* C. FOR A TIME PERIOD IN THE RANGE OF 1/2 TO 5 HOURS, THE MOLAR RATIO BETWEEN THE DICYANDIAMIDE AND THE ACID BEING IN THE RANGE OF 1:1 TO 1:4, TO FORM A FIRST STAGE REACTION PRODUCT, MIXING THE FIRST STAGE REACTION PRODUCT WITH FORMALDEHYDE IN A MOLAR RATIO BETWEEN 2 TO 5 MOLES OF FORMALDEHYDE PER MOLE OF DICYANDIAMIDE USED IN THE FIRST STAGE REACTION AND HEAT REACTING THE FIRST STAGE REACTION PRODUCT WITH FORMALDEHYDE IN THE PRESENCE OF WATER IN A SECOND STAGE REACTION TO FORM A SECOND STAGE REACTION PRODUCT, AND HEAT REACTING THE SECOND STAGE REACTION PRODUCE IN A THIRD STAGE REACTION WITH A WATER-SOLUBLE SALT SELECTED FROM THE GROUP CONSISTING OF AN ALUMINUM ACETATE HAVING THE FORMULA AI(OH)2 (CHOCOO). 1/3H3BO3 ALLUMINUM FORMO ACETATE HAVING THE FORMULA
