Abstract:
A solid, colored, shaped wax-based article consisting essentially of:a natural, and/or synthetic wax, a colorant, and and a compound of the formula (1) â€ƒwherein R1 is independently C1-20 alkyl, C1-20 alkoxyalkyl, C1-20 hydroxyalkyl, C1-20 alkenyl, substituted C1-20 alkenyl groups, C1-20-alkoxy-C1-20-alkyl groups, C1-20-oxy-N-C1-20-alkyl groups, â€”N-cyclic-C1-10-alkyl groups, or cyclic-N-C1-10-alkyl groups; R11 is hydrogen or C1-C8 alkyl; p and q are independently 0 or 1; Ar is a substituted aromatic single ring, an unsubstituted aromatic single ring, a substituted aromatic fused 2 or 3 ring group, an unsubstituted aromatic fused 2 or 3 ring group, a heteroaromatic single ring, or a heteroaromatic fused 2 or 3 ring group; R3 is hydrogen, C1-C18alkyl, C5-C12cycloalkyl unsubstituted or mono-, di- or tri-substituted by C1-C4alkyl, or C7-C9 phenylalkyl unsubstituted or mono-, di- or tri-substituted on the phenyl by C1-C4alkyl, or a hindered amino group selected from (i) to (xi): â€ƒwherein R, Râ€², Râ€²1, Râ€²2 and R5 are independently either hydrogen, C1-12alkyl, C1-8alkoxy, or â€”COR3â€², where R3â€² is hydrogen, C1-16alkyl, phenyl, â€”COO(C1-4alkyl) or NR15R16, where R15 and R15 are independently hydrogen, C1-12alkyl, C5-6cycloalkyl, phenyl or (C1-12alkyl)phenyl; or R15 and R16 together with the N-atom to which they are attached form a five- to seven-membered ring which may contain an additional N- or O-atom; n is 0 or 1 (structure iv); Y is the group â€”NCO or â€”OCN, where CO forms part of the cyclic structure; each R6 of structure (iii) independently is selected from hydrogen, C1-12alkyl or phenyl provided only one R6 can be phenyl, or both groups R6 together form the group â€”(CH2)mâ€”; where m is 2 to 11, â€”C(CH3)2â€”, â€”C(CH3)2â€”CH2â€”CH2â€” or â€”C(CH3)CH2CH2CH(CH3)â€”.
