Abstract: Leuco dye compositions containing a compound of the formula: ##STR1## wherein m = 0 or 1: Ar is an arylene or lower alkyl substituted arylene radical;R.sub.1 and R.sub.2, which may be the same or different, are lower alkyl or hydroxyalkyl groups, or ##STR2## R.sub.3 is H, lower alkyl, benzyl, R.sub.4, or ##STR3## R.sub.5 is H, a C.sub.3 -C.sub.6 alkyl group, an aryl group, ##STR4## wherein n=2-6; and R.sub.6 is a lower alkyl group or an aryl group. Where m = 1, the formula represents a colorless leuco compound; where m = 0, the formula represents the yellow dye derivative of the leuco. These compounds are particularly useful in photosensitive compositions.

Abstract: Hydroxy higher alkyl morpholine oxides, and formulations containing the same. The compounds have many beneficial effects in detergent and cosmetic compositions, particularly desirable for application to the skin and for modification of foaming power of detergent compositions.

Abstract: A sunscreening composition comprising a highly substantive sulfonium salt sunscreening agent represented by the formula: ##STR1## wherein A is a sunscreening moiety, having a prominent spectral absorption peak within the range of 250-400 millimicrons; R represents alkylene of from 2 to 18 carbon atoms; R' and R" represent alkyl, and wherein the sum of the carbon atoms in R' and R" is not less than 9 and not greater than 27, and wherein the nitrogen is linked to A as a carboxamido or sulfonamido group, and X is an anion, in a carrier.

Abstract: The present invention relates to thioether compounds represented by the formula A--NH--R--S--R' wherein A is a sunscreening moiety having a prominent spectral absorption peak within the range of 250-400 millimicrons, R is an alkylene of from 2 to 18 carbon atoms and R' represents an alkyl group containing from 7 to 26 carbon atoms. Such thioethers are intermediates employed in the synthesis of sulfonium salt sunscreen agents having improved adhesion to the skin.

Abstract: Sunscreening agents having improved adhesion to human skin comprising a polymeric material having a sunscreening group, e.g., a salicylate, aminobenzoate or a para-carboxy succinanilic acid group and having a substrate-binding group, e.g., a thioacetate, mercaptan, guanidyl or biguanidyl group. A representative species is a copolymer of vinylthioacetate and vinyl salicylate.

Abstract: Extremely bright, tinctorially strong disperse dyes derived from diaminomaleonitrile and selected aromatic and heterocyclic aldehydes, and their preparation, useful for dyeing and printing polyester and polyester-cotton blend fibers in yellow to blue shades of generally good fastness properties, which dyes are of the general formulaAr.sub.1 -CH=N-C(CN)=C(CN)-N=CH-Ar.sub.2wherein Ar.sub.1 and Ar.sub.2 are aromatic or aromatic-like groups, for example, phenyl or pyridyl.

Abstract: Compounds of the general formula: ##SPC1##Wherein m = 0 or 1;Ar is an arylene or lower alkyl substituted arylene radical;R.sub.1 and R.sub.2, which may be the same or different, are lower alkyl or hydroxyalkyl groups, or ##EQU1## R.sub.3 is H, lower alkyl, benzyl, R.sub.4, or ##EQU2## R.sub.4 is ##SPC2##Alkyl group, an aryl group, ##EQU3## wherein n=2-6; and R.sub.6 is a lower alkyl group or an aryl group. Where m = 1, the formula represents a colorless leuco compound; where m = 0, the formula represents the yellow dye derivative of the leuco. These compounds are particularly useful in photosensitive compositions.

Abstract: A body limb support comprising a limb encircling member comprising knitted thread wherein the outer parts of the knitted thread in a relaxed state on a substantial portion of the inner surface of the limb encircling member have attached thereto a nonadhesive, noncontinuous, relatively soft, elastomeric polymeric material with a high coefficient of friction to skin so as to provide a nonocclusive slip resistant surface capable of maintaining the support in place on the limb of the body.
