Patent ID: 7323534

Claim:
A resin comprising the reaction product of a composition comprising: a hydroxyaromatic compound; about 0.025 to about 0.40 moles of alkaline catalyst per mole of hydroxyaromatic compound; an aldehyde, wherein the initial molar ratio of hydroxyaromatic compound to aldehyde is about 2.0:1 to about 6.0:1; and a urea-aldehyde condensate, wherein the urea-aldehyde condensate is previously formed from urea and an aldehyde at a temperature of about 50 to about 80° C. for a time effective to form a reaction product having a free aldehyde concentration of about 1 to about 35 weight %; and wherein the amount of urea present in the resulting resin is about 1 to about 40% by weight of the total solids.
