Abstract

1,138,551. Phenolic-resin composition. RANK XEROX Ltd. 17 Jan., 1966 [18 Jan., 1965], No. 2196/66. Heading C3R. [Also in Division H1] The invention comprises a charge-transfer complex of a phenol-aldehyde resin and a Lewis acid. Preferably the resin has the formula where R is a residue selected from formaldehyde, paraformaldehyde, furfural, amino formaldehyde, acrolein, benzaldehyde, chloral, oxoaldehydes, acetaldehyde, glyoxal, propionaldehyde, n-butyraldehyde, isobutyraldehyde, nvaleraldehyde, isovaleraldehyde, n-coproaldehyde, n-heptaldehyde, stearaldehyde and crotonaldehyde or mixtures thereof; Y is H, OH, halogen or lower alkyl X is O or R Z is an integer of at least 2 n is an integer up to 4 and m is an integer up to 3. In the examples the resins used are a dimethyl diphenyl oxide-phenol resin modified with diphenyl oxide, rosin modified phenolformaldehyde, phenol-formaldehyde and pphenyl phenol-formaldehyde whilst the Lewis acids used are 2,4,7-trinitrofluorenone, benzophenone tetracarboxylic acid, benzanthracene- 7,12-dione, aurintricarboxylic acid, 1,3,5-trinitrobenzene, 2,3-dichloro-1 ,4-naphthaquinone. Ethyl methacrylate resin may be used as a binder together with sensitizers such as pyronin B, methylene green, brilliant green and eosine Y. Numerous other Lewis acids of the organic and the inorganic types are specified. Also listed are phenols which may be used to form the phenol-aldehyde resin. The photoconductive material may be coated on Al foil to form an electrophotographic plate or may be used as a self-supporting transparent sheet.
