Patent ID: 8293699

Claim:
A hydrophilized article, comprising: (a) a substrate having a hydrophobic hard surface, and (b) a hydrophilizing layer disposed on at least a portion of the hydrophobic surface of the substrate, said layer comprising: (b)(I) an organophosphorus material selected from the group consisting of: (b)(I)(1) organophosphorus compounds according to structure (I): wherein: each R 1 is and each R 2 is independently absent or O, provided that at least one of R 1 and R 2 is O, each R 3 is independently selected from the group consisting of alkyleneoxy and poly(alkyleneoxy), which may optionally, be substituted on one or more carbon atom of such alkyleneoxy, or poly(alkyleneoxy) group by a substituent selected from the group consisting of hydroxyl, alkyl, hydroxyalkyl, alkoxy, alkenyl, aryl and aryloxy, R 5 is and each R 4 is independently absent or selected from the group consisting of alkyleneoxy and poly(alkyleneoxy), which may optionally, be substituted on one or more carbon atom of such alkyleneoxy, or poly(alkyleneoxy) group by a substituent selected from the group consisting of hydroxyl, alkyl, hydroxyalkyl, alkoxy, alkenyl, aryl and aryloxy, R 6 and R 8 are each and each R 7 is independently selected from the group consisting H and -POR 9 R 10 , R 9 and R 10 are each independently selected from the group consisting of hydroxyl, and m is an integer of from 2 to 5, (b)(I)(2) salts of organophosphorus compounds according to structure (I), (b)(I)(3) condensation reaction products of two or more molecules of one or more organophosphorus compounds according to structure (I), wherein m of each said molecule is an integer from 1 to 5, and (b)(I)(4) mixtures comprising two or more of the compounds, salts, and/or reaction products of (b)(I)(1), (b)(I)(2), and (b)(I)(3);
