free aldehyde, which comprises adding hydrogen peroxide
to the melamine and aldehyde reaction product under pH
conditions of between 1.0 and 2.5.
14. An acidic aqueous solution of melamine-aldehyde polymer
containing free aldehyde levels below 0.1% by weight
produced by a method as claimed in claim 1.
The references relied on by the examiner are:
Ross et al. (Ross) Sep. 15, 19643,148,937
Murchison et al. (Murchison) 3,819,516 June 25, 1974
