| titleOfInvention | Process for tinting a resin for optical materials |
| abstract | A process for tinting a resin for optical materials comprises dipping a resin for optical materials into a liquid comprising an inorganic acid and/or an organic acid and thereafter tinting the resin, wherein the organic acid is a mixture of compound (I) having sulfo group and compound (II) having phenolic hydroxyl group but not having sulfo group and the ratio Ä(I)/(II)Ü of the amount by weight of compound (I) to the amount by weight of compound (II) is 0.01 to 2.0. The resin for optical materials is preferably a resin containing sulfur. The resin for optical materials may be a resin obtained by curing by polymerization of a compound having one or more structures represented by the following formula (1) in one molecule or a composition comprising said compound: <CHEM> wherein R<1> represents a hydrocarbon group having 1 to 10 carbon atoms, R<2>, R<3> and R<4> each represents hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms, Y represents S or O, n represents 0 or 1, m represents a number of 1 to 5 and n represents a number of 0 to 5. The resin for optical materials may also be a resin obtained by curing by polymerization of a compound having one or more structures represented by the following formula (1') in one molecule or a composition comprising said compound: <CHEM> wherein R<1> represents a hydrocarbon group having 1 to 10 carbon atoms, R<2>, R<3> and R<4> each represents hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms, j represents a number of 1 to 5, k represents a number of 0 to 5, j+k represents a number of 2 or larger and j and k do not represent 1 simultaneously. The inorganic acid is preferably at least one compound selected from the group consisting of hydrochloric acid, sulfuric acid, nitric acid and phosphoric acid. The organic acid is preferably a compound having at least one group selected from the group consisting of sulfo group, carboxyl group and phenolic hydroxyl group. A resin for optical materials tinted in accordance with the above process is also provided. |
