Resinous products prepared by condensing a diphenylol cycloparaffin with formaldehyde, in the presence or absence of other synthetic resin components, e.g. diphenylol propane, urea, or toluene sulphonamide, and in the presence or absence of an acid, neutral or alkaline catalyst are used as ingredients of compositions having a basis of cellulose ester or ether. Thus, lacquers &c. may be made from a cellulose ester or ether and a resin prepared as described above; such lacquers &c. may include also other synthetic resins, e.g. fusible and soluble phenol-formaldehyde or diphenylolpropane-formaldehyde resins, preferably those prepared in the presence of an acid catalyst, phenolfurfural resins, and resins from formaldehyde or furfural and toluene sulphonamide, semi-synthetic resins, e.g. ester gum, natural resins, e.g. manila, acaroid resins, pontianak, kauri, dammar, rosin, and shellac, plasticizers, e.g. diphenylol propane, xylene monomethylsulphonamide, toluene o- or m-ethylsulphonamide, fire retardants, e.g. bromtricresyl phosphates, and the usual pigments &c. Solvents that may be used in so applying the resins include acetone, ethyl alcohol, benzene, ethylene dichloride, ethyl acetate and lactate, tetrachlorethane, benzyl alcohol, and diacetone alcohol. Examples are given describing (1) a coating composition containing cellulose acetate, diphenylol-cyclohexane-formaldehyde resin, and acetone; (2) a coating composition containing cellulose acetate, diphenylol-cyclohexane-formaldehyde resin, acetone, benzene, ethyl alcohol, and ethyl lactate; (3) a coating composition containing cellulose nitrate, diphenyl-cyclohexane-formaldehyde resin, camphor, diethyl phthalate, benzene, ethyl and butyl alcohols, and ethyl and butyl acetates; (4) a lacquer containing cellulose acetate, diphenylol-cyclohexane-formaldehyde resin, diphenylol propane, acetone, benzene, toluene, ethyl acetate and lactate, and a pigment. The manufacture of products having a basis of cellulose formate, propionate, or butyrate, or of methyl, ethyl, or benzyl cellulose is referred to. Specification 342,429 is referred to.ALSO:Resinous products are prepared by condensing a diphenylol cycloparaffin with formaldehyde. Mixed products may be obtained by including in the reaction mixture other synthetic resin components, e.g. diphenylol propane, urea, or toluene sulphonamide. The condensation may be effected in the presence of an acid, neutral, or alkaline catalyst. In an example, equimolecular proportions of diphenylol cyclohexane and formaldehyde solution are heated under reflux with the addition of a catalyst, e.g. hydrochloric or boric acid, and the product is washed with water. It may be purified after solution in caustic soda or alcohol, and then distilled at ordinary or reduced pressure to remove water &c., and after or during the distillation it may be hardened by heating at 140-150 DEG C. The diphenylol cyclohexane used may be the pure compound or a crude product obtained by condensing phenol with cyclohexanone (cf. Specification 342,429). The resinous products prepared as described above are useful as ingredients of compositions having a basis of cellulose ester or ether. Thus, lacquers, varnishes, plastic masses, &c., may be made from a cellulose ester or ether and a resin prepared as described above; such lacquers &c. may include also other synthetic resins, e.g. fusible and soluble phenol-formaldehyde or diphenylolpropane-formaldehyde resins, preferably those prepared in the presence of an acid catalyst, phenolfurfural resins, and resins from formaldehyde or furfural and toluene sulphonamide, semi-synthetic resins, e.g. ester gum, natural resins, e.g. manila, acaroid resins, pontianak, kauri, dammar, rosin, and shellac, plasticizers, e.g. diphenylol propane, xylene monomethylsulphonamide, toluene o- or m-ethylsulphonamide, fine retardants, e.g. bromtricresyl phosphates, and the usual pigments &c. Solutions comprising a cellulose derivative and a resin prepared as described above may also be used for the manufacture of artificial filaments by dry or wet spinning, or for the manufacture of films. Solutions comprising a resin prepared as described above, with or without a cellulose derivative, may also be used as adhesives, particularly for the manufacture of laminated glass, the intermediate material of which may itself have a basis of cellulose derivative. Solvents that may be used in applying the resins as described above include acetone, ethyl alcohol, benzene, ethylene dichloride, ethyl acetate and lactate, tetrachlorethane, benzyl alcohol, and diacetone alcohol. Examples are given describing: (1) a coating composition containing cellulose acetate, diphenylol-cyclohexane-formaldehyde resin, and acetone; (2) a coating composition containing cellulose acetate, p diphenylol-cyclohexaneformaldehyde resin, acetone, benzene, ethyl alcohol, and ethyl lactate; (3) a coating composition containing cellulose nitrate, diphenylol-cyclohexaneformaldehyde resin, camphor, diethyl phthalate, benzene, ethyl and butyl alcohols, and ethyl and butyl acetates; (4) an adhesive, useful in making laminated glass, containing cellulose acetate, diphenylol-cyclohexane-formaldehyde resin, acetone, and ethyl acetate and lactate; (5) an adhesive, useful in making reinforced glass, comprising cellulose nitrate, a diphenylol-cycloparaffin-formaldehyde resin, camphor, dibutyl phthalate, benzene, ethyl and butyl alcohols, and ethyl and butyl acetates; (6) a plastic composition containing cellulose acetate, diphenylol-cyclohexane-formaldehyde resin, xylene monomethyl sulphonamide, ethyl alcohol, and benzene; (7) a plastic composition containing cellulose acetate, diphenylol-cyclohexane-formaldehyde resin, diphenylol cyclohexane, ethyl alcohol, and benzene; (8) a solution, suitable for making artificial filaments by dry spinning, containing cellulose acetate, diphenylol-cyclohexaneformaldehyde resin, and acetone; (9) a lacquer containing cellulose acetate, diphenylol-cyclohexaneformaldehyde resin, diphenylol propane, acetone, benzene, toluene, ethyl acetate and lactate, and a pigment.
