Abstract (en)
[origin: WO2007141114A1] The invention relates to formaldehyde-free, carbonyl- and ring-hydrogenated ketone-aldehyde resins based on alkyl aryl ketones and formaldehyde which have a low OH functionality, a low proportion of compounds capable of crystallization, a low viscosity, a very low colour number and a very high heat and light stability and also a process for preparing them.
