Abstract: Heat stable, negative resist compositions are provided for use, particularly in deep ultraviolet light x-ray and electron beams. The composition comprises an acid generting onium salt photoinitiator, a source of polyfunctional activated aromatic rings and a source of polyfunctional carbonium ions, with at least one of said sources being a polymer.

Abstract: A substrate is planarized by applying a liquid coating to it comprising a polyamide alkyl ester formed from a pyromellitic alkyl diester and a para-linked aromatic diamine dissolved in a solvent containing at least 10% of a co-solvent boiling above 220 DEG C, and curing the coating.

Abstract: Substrate comprises (1) leucomethylene blue dye (I) and (2), as stabiliser, citric, aspartic, malonic, oxalic, ascorbic or tartaric acids; ketomalonic acid monohydriate; glucose or methionine. Most pref. is malonic acid. Pref. the mole ratio of (I):stabiliser is about 1:1 and the substrate, which is esp. paper, may also contain bromide ions. Typically the paper is treated with an aq. soln. contg. 0.5-5 (1) wt. %(I), a stoichiometric amt. of stabiliser and 1-30(15)% bromide ion. Each 8.5 by 11 inch sheet of paper contains about 10 mg (I). The stabiliser inhibts background formation, i.e. oxidative conversion of (I) to the coloured form. The substrates are most useful for electrochromic printing and give prints of improved storage qualities.
