The present invention provides a salt of the formula (I):
wherein ring Y represents monocyclic or polycyclic hydrocarbon group having 3 to 30 carbon atoms, in which one —CH
2
— group is substituted with —COO— group, and at least one hydrogen atom in the monocyclic or polycyclic hydrocarbon group may optionally be substituted with alkyl group having 1 to 6 carbon atom, alkoxy group having 1 to 6 carbon atom, perfluoroalkyl group having 1 to 4 carbon atoms, hydroxyalkyl group having 1 to 6 carbon atoms, hydroxyl group or cyano group; Q
1
and Q
2
each independently represent fluorine atom or perfluoroalkyl group having 1 to 6 carbon atoms; A
+
represents organic counter ion; and n shows an integer of 0 to 12.
The present invention also provides a chemically amplified resist composition comprising the salt of the formula (I).
A rheology modifier/hair styling resin which is a crosslinked, linear poly(vinyl amide/polymerizable carboxylic acid) copolymer exhibits advantageous hair care properties of high viscosity and long-lasting curl retention.

Described herein are compounds (III) comprising an indeno[2',3', 3, 4] naptho [1,2-b] pyran structure. Such compounds may be useful for their photochromic properties, and be use in certain photochromic compositions. Such compositions may further comprise other photochromic compositions and/or materials. Additionally, such compounds and/or compositions may be suitable for preparing certain photochromic articles.
Isoquinoline and quinoline have been discovered as novel ligands for palladium-catalyzedoxidative cascade cyclization reactions. With our new catalyst systems (Pd(OAc)2/isoquinoline or quinoline), unsaturated anilides cyclize under an oxygenatmosphere (1 atm) to furnish structurally versatile indoline derivatives in good yields. One C−N bond and two C−C bonds are formed in a single step with excellent
