A MODIFIED RESINOUS COMPOSITION WHICH, WHEN CURED, EXHIBITS IMPROVED DIELECTRIC PROPERTIES UNDER EXTENDED WET CONDITIONING WHICH COMPRISES A BLEND OF (A) A RESINOUS REACTION PRODUCT OF (1) AN AMINOTRIAZINE-ALDEHYDE RESIN HAVING A MOL RATIO OF ALDEHYDE:AMINOTRIAZINE OF FROM ABOUT 1.5:1 TO ABOUT 6:1, RESPECTIVELY, AND (2) AT LEAST ABOUT 2% BY WEIGHT, BASED ON THE TOTAL WEIGHT OF RESIN SOLIDS IN SAID (1), OF A MONOMERIC AMINOTRIAZINE, EACH OF THE AMONOTRIAZINE COMPONENTS OF SAID (A) INITIALLY CONTAINING AT LEAST TWO AMIDOGEN GROUPS EACH HAVING AT LEAST ONE ALDEHYDE-REACTABLE HYDROGEN ATOM ATTACHED TO THE AMIDOGEN NITROGEN ATOM, THE MOL RATIO OF ALDEHYDE:AMINORIAZINE IN SAID (A) BEING FROM ABOUT 1.45:1 TO ABOUT 1.95:1, RESPECTIVELY, SAID (A) HAVING BEEN PREPARED BY REACTING SAID (1) AND SAID (2) AT A TEMPERATURE OF FROM ABOUT 40* C. TO ABOUT 100* C. UNTIL THE RESIN SOLIDS AT MAXIMUM DILUTION AT 30* C. RANGED FROM ABOUT 20% TO ABOUT 35% BY WEIGHT, AND (B) FROM ABOUT 0.1% TO ABOUT 1.5% BY WEIGHT, BASED ON THE TOTAL WEIGHT OF RESIN SOLIDS PRESENT, OF ANY ALKYLENE POLYAMINE.
