    摘要: A plastic article having improved surface characteristics comprises a plastic body having adhered thereon a cross-linked film of a composition comprising (A) 10 to 90 parts by weight of a cross-linking unsaturated compound having a molecular weight of M and containing in the molecule N polymerizable ethylenically unsaturated radicals (N being an integer of 2 or more), the ratio of said molecular weight, M, to said number, N, of ethylenically unsaturated radicals (M/N) being about 49 to about 600, (B) 90 to 10 parts by weight of an unsaturated monomer containing in the molecule at least one radical copolymerizable with said component (A) and at least one acid radical, and (C) up to 20 parts by weight of other copolymerizable unsaturated compounds, the total of (A), (B) and (C) being 100 parts by weight, at least a part of the acid radicals contained in the film having been converted into alkali salts thereof, said cross-linked film having a thickness of 5 to 500 .mu.. The above plastic article is produced by forming on the surface of a plastic body a cross-linked film of the composition comprising the components (A), (B) and (C) and then treating the cross-linked film with a base to convert the acid radical into its alkali salt.

    摘要: A cathode ray tube having degaussing coils attached to an outer side of a glass vessel of a funnel part of a main body of the cathode ray tube, in which the degaussing coils each include a flattened part, extended along the outer front surface at a front side of a funnel part, a circular part having a circular cross-section and a transition part interconnecting the end parts of the flattened part and the circular part and changed in cross-section shape from a flattened rectangle to a circle. The degaussing coil may has shape flattened partially to reduce the outer size of the cathode ray tube and includes a plastic case for retaining the coil in the flattened shape. The degaussing coil is stabilized in shape and is not deformed during transport while its attachability with respect to the cathode ray tube may be improved.
