Abstract
1485733 Cationic melamine-formaldehyde resins NIPPON CARBIDE KOGYO KK 8 Jan 1975 [14 Jan 1974] 795/75 Heading C3R [Also in Division C1] Water-soluble melamine resins containing in the molecule units of formula wherein, X is an anion, are prepared by reacting 1 mole of melamine with 2-3 moles of formaldehyde and optionally with less than 1 mole of urea, dicyandiamide or acetoguanamine and adding to the resulting methylol melamine resin solution 0À5-3À5 moles of acid per mole of melamine. In examples melamine is reacted with aqueous formaldehyde solution at pH8 and then (a) further reacted with formic acid or (b) spray dried and the resultant powder dissolved in dilute hydrochloric acid. Specification 1,210,517 is referred to.
