    Abstract: Mixture of resins having repeating units of formula

    wherein R1 is di or trivalentaryl, Ar is the residue of a phenol with 1-3 hydroxy groups and at least 2 nuclear carbon atoms and n is 0 or 1 and 0.5 - 100% of a heat stable inorganic dispersing agent with 1 dimension less than 100m Mu and all dimensions less than 15 Mu can reduce cissing and blistering in cured products and can enable combinations of said mixtures with particulate materials of particle size 0.2 Mu - 2mm to be evenly dispersed in organic solvents. Uncured formaldehyde condensates with nitrogenous compounds containing a N C - NH2 group (or enolisable group thereof) cure the above resins.
