Abstract
To obtain resinous products which may be used without a binder to form the photoconductive layers of electro-photographic materials various organic photo-conductors are reacted with isocyanate and/or epoxy components. In one embodiment (Example 5) the bisglycidyl ether of ethylene glycol is reacted with 4-[N-ethyl-N-(b -hydroxy ethyl) amino]-benzophenone at 170 DEG C. under nitrogen and the unreacted ether removed under vacuum. The residue is dissolved in cyclohexanone and reacted for a short time at 100% with a modified tri-isocyanate. In another embodiment (Example 8) 3 - amino - a - (41 - dimethylaminocinnamal) -acetophenone is added to an ethyl amyl ketone solution of a partly condensed epoxy resin obtained from diphenol propane and epichlorhydrin, and is reacted under reflux at 100 DEG C. To form a photoconductive layer the reaction mixture is diluted with methyl isobutyl ketone and methyl ethyl ketone and a small quantity of a modified tri-isocyanate added with sensitizing dyes-the mixture is coated on to a support and the solvents allowed to evaporate. In a further embodiment (Example 4) a cyclohexanone solution of 2-hydroxy-4-diethylamino - 21 - carboxy - benzophenone (containing a small amount of Rhodamine B) is mixed with a concentrated solution in ethyl acetate of a modified triisocyanate obtained by reacting 1 mol of tri-methylol propane and 3 mol of toluylene-2: 4 and/or 2: 6-diisocyanate. Condensation is effected at 151 DEG C. and the product thrown out of solution by the addition of acetone. In a further embodiment (Example 7) 2 - hydroxy - 4 - dimethylamino - a - [4 - (methylb -hydroxyethy - amino) - cinnamal] - acetophenone and a concentrated ethyl acetate solution of a modified triisocyanate are dissolved in cyclohexanone and reacted at 150 DEG C. The reaction mixture is diluted with methyl ethyl ketone and ethyl amyl ketone to form the coating composition. In another embodiment (Example 9) an isocyanate component is made by the reaction at 148 DEG C. of 2-ethyl-2-butylpropan-1 : 3-diol with toluylene-2: 4-(or 2: 6)-diisocyanate. The purified product is dissolved in cyclohexanone with 4-dimethylamino-phenyl-31-hydroxy-naphthyl-(21)-ketone and condensed at 135 DEG C. to obtain a solution of the photo-conductive product. In another embodiment (Example 17) a concentrated ethyl acetate solution of a modified tri-isocyanate is dissolved in cyclohexanone with 2: 4-di-hydroxybenzophenone, and initially reacted under reflux at 150 DEG C. The temperature is then mixed to 200 DEG C.-the cyclohexanone distills off. The resin left is dissolved in mixed solvents to obtain the coating composition.ALSO:<FORM:1008633/C2/1> <FORM:1008633/C2/2> <FORM:1008633/C2/3> In Examples (6), (12) and (16), the trisiso-cyanate obtained from trimethylolpropane (1 mol.) and tolylene diisocyanate (3 mols.) is reacted with the compounds of the formulae given in Figs. 8, 23 and 21 respectively. In Example (12), n-dodecyl alcohol is also present. The product of Example (16) is further reacted with di-(2-ethylhexyl) amine.
