Abstract

The invention provides a process for preparing solutions of curable aminosulphonic acid-modified urea- formaldehyde resins. These solutions are prepared according to a known process modified by adding, in the initial reaction stage, 1-10 wt%, based on resin solids of an emulsion or suspension of a polymer derived from monomers of formula <IMAGE> wherein R<1> is H or CH<3>, R<2> is O, R<3> is OH, NH2, OCnH2n+1, OCmH2mOH or OCmH2mOCnH2n+1, wherein m is an integer from 1 to 6 and n is an integer from 1 to 4, or R<2> and R<3> conjointly are N. The solution formed by this process is suitable for impregnating and coating carrier webs, the resin then being cured. Such treated carrier webs are particularly useful for application to a surface of a wood-based sheet in, for example, a quick-cycling press or a multi-daylight press resulting in improvement in properties of the surface of the wood-based sheet.
