Abstract
Melamine resins are effectively elasticized with an elasticizer having the formula R-C.sub.6 H.sub.4 --COO--X--OH wherein C.sub.6 H.sub.4 denotes a phenylene group, R denotes a hydrogen atom or a methyl or ethyl group, and X denotes an unbranched or branched alkylene group with 2 to 6 carbon atoms whose carbon chain is either uninterrupted or interrupted by one oxygen atom. Such elasticized resins are particularly suitable for bonding together laminates.
