Claim 1
Independent Claim
85 words
A FLEXIBLE POLYETHYLENE BOTTLE HAVING A HARD, GLOSSY, ADHERENT SURFACE COATING COMPOSED OF A CURED REACTION PRODUCT OF ABOUT 100 PARTS OF AN EPIHLORHYDRIN-POLYHYDRIC PHENOL CONDENSATE HAVING AN EPOXIDE EQUIVALENT BETWEEN ABOUT 160 AND 200, ABOUT 35 TO 70 PARTS OF A UREAFORMALDEHYDE RESIN, ABOUT 8 OT 20% (BASED ON THE COMBINED WEIGHT OF SAID CONDENSATE AND UREA-FORMALDEHYDE RESIN PRESENT) OF AN EPOXIDIZED FATTY ACID ESTER OIL, ABOUT 3 TO 8 PARTS OF H3PO4(BASED ON THE COMBINED WEIGHT OF SAID CONDENSATE AND SAID UREA-FORMALDEHYDE RESIN).
