Abstract

1,244,021. Tenesbrescent materials and uses thereof. MINNESOTA MINING & MFG. CO. 23 Aug., 1968 [25 Aug., 1967], No. 4O522/68. Heading C4S. [Also in Divisions G1 and H1] A semi-conductive layer which is both photoconductive and photochromic comprises at least one 1 - carboxamidoanthraquinone (specific examples disclosed) in which the nitrogen atom is directly bonded to the nucleus and has a hydrogen atom directly bonded thereto and at least an equimolar quantity of at least one amine having a pK b value not greater than that of benzylamine. Further the anthraquinone and amine together have an electron spin resonance value of at least one when measured in an inert solvent at a 0 01 molar concentration, and provide a minimum ratio of light conductivity to dark conductivity of 50. In the examples a photochromic member is made using a compound of formula which is both a carboxamido-anthraquinone and an amine. The layer may be self-supporting or deposited on to a substrate of aluminized polyester sheet either as a powder or dispersed in copoly(vinyl alcohol - vinyl acetate - vinyl butyral), copoly styrene - butadiene or chloroform. Potassium bromide may be added to form colour centres or eosin or erythrosin used as sensitizers. Irradiation of the layer generates stable free radicals and changes the colour of the layer. The colour change is reversed by the presence of paramagnetic compounds such as O 2 , N 2 0 or Cu<SP>2</SP>+. In use the layer is normally protected by a layer of polyvinyl alcohol which is stripped away to erase the image pattern formed. The layer is sensitive to an electron beam. Applications include electron beam recording layers imaging layers, sunglasses, light modulation, light filtration and for monitoring oxygen leakage in vacuum devices containing special foods and medecines for example, the magnitude of the colour change in the latter instance being a measure of light and also oxygen available. In an imaging device, for example, the compound may be mixed with a styrene/butadiene copolymer and coated on the polyester side of an Al coated polyester sheet and a p.v.a. film coated thereon until erasure of a black image produced by illumination through a negative or by an electron beam was required, when removal of the p.v.a. layer effected reversal to the original state. In an embodiment using acrylate resin latex top coat, the restoration was a function of its oxygen permeability. Alternatively, after use in a thermographic copying process, the image produced in the original sheet by light exposure, may be removed by heating.
