摘要:
The present invention relates to a compound having the structure of Formula I:
A-N=N-Z I
wherein: A is an optionally substituted aryl radical; Z is the residue of a moiety selected from dimedone (5,5-dimethy-1,3-cyclohexanedione), acetoacetamides, malonamides, barbituric acid and 1,3-propanediones; wherein the compound comprises at least one ethylenically-unsaturated polymerizable group (Q).
摘要:
Polymerizable light absorbing azo dyes are disclosed useful as monomers in the formation of devices such as, but no limited to ocular lenses. Specifically, intraocular lenses (IOL) are disclosed wherein one or more of the light absorbing dye is covalently bonded to other structural polymers though ethylene unsaturated groups. The resulting IOLs possess light absorbing properties without significant amounts of free (un-bound) azo dye molecules present in the final structural polymer matrix.
摘要:
An ink composition is disclosed which contains a novel type of dye (CG) n (SAU) m that is capable of assembling with a compound (SAU") p (X) q , thus forming supramolecular structures. Also disclosed is an ink jet printing process using these novel dyes, and an ink jet printing apparatus provided with an ink cartridge containing such a dye.
