摘要： Process for the preparation of a novolac alkylphenol resin using a defined mixture of mono- and dialkylphenols, an aldehyde, and an acid catalyst. The mixture of mono- and dialkylphenols comprises 20 to 70 mol % mono-alkylphenols having an alkyl group of 1 to 18 carbon atoms, and 30 to 80 mol % of dialkylphenols having alkyl groups of 1 to 18 carbon atoms. The molar ratio of aldehyde in comparison to the mono- and dialkylphenol mixture is greater than or equal to 1. Novolac alkylphenol resins prepared according to this invention contain, of each individual starting material phenolic monomer component, less than 0.5 mass %, and in the best case, less than 0.1 mass % in comparison to the total obtained alkylphenol resin.

摘要： The present invention provides an energy-sensitive resin composition with which it is possible, even if the precursor polymer is heat-treated at low temperatures, to produce a film or molded article comprising an imide ring-containing polymer having excellent heat resistance, tensile elongation and chemical resistance with a low dielectric constant, or a film or molded article comprising an oxazole ring-containing polymer having excellent heat resistance, tensile elongation and chemical resistance. Also provided are a method of manufacturing the film or molded article; a method of forming a pattern using the energy-sensitive resin composition; and a permanent film having excellent heat resistance, tensile elongation and chemical resistance. The energy-sensitive resin composition comprises an imidazole compound (A) represented by formula (1a), a resin precursor component (B), and a solvent (S), wherein the resin precursor component (B) is at least one resin precursor component selected from the group consisting of: a monomer component comprising a diamine compound represented by formula (2), a dicarbonyl compound represented by formula (3a) and/or a tetracarboxylic acid dianhydride represented by formula (3b); and a precursor polymer having a repeating unit represented by formula (4).
