    摘要: Disclosed is a color-developing composition for pressure-sensitive recording sheet material of the self-contained type comprising (A) 100 parts by weight of a copolymer obtained by reacting a p-alkylphenol having an alkyl moiety of from 1 to 12 carbon atoms and phenol with formaldehyde and (B) from 1 to 20 parts by weight of a hindered phenolic compound selected from phenols having an alkyl, alkylene or hydroxyl substituent radical in at least the 2- or 6-position, or both, of the benzene ring and derivatives thereof, the copolymer and the hindered phenolic compound being homogeneously dissolved in mutual solution. The hindered phenolic compound is either added to the starting materials for the preparation of the copolymer or, at the end of the copolymerization reaction, added to the resulting copolymer and dissolved homogeneously in mutual solution.

    摘要: This invention relates to molding resin compositions, and more particularly relates to polyimide resin compositions having markedly improved molding ability in addition to excellent high temperature stability, chemical resistance and mechanical strength.The polyimide resin composition of this invention comprises 99.9 to 50% by weight of the polyimide and 0.1 to 50% by weight of high temperature engineering polymer. The polyimide has recurring units of the following formula: ##STR1## wherein X is a sulfonyl radical or a carbonyl radical and R is a tetravalent radical selected from an aliphatic radical, alicyclic radical, monoaromatic radical, condensed aromatic radical and non-condensed aromatic radical. R is, for example, ##STR2## The high temperature engineering polymer is, for example, polyphenylene sulfide consisting of recurring units of the formula: ##STR3## aromatic polysulfone consisting of recurring units of the formula: ##STR4## or aromatic polyetherimide consisting of recurring units of the formula: ##STR5##
