copolymers comprising (i) at least one unit of at least one monomer
chosen from maleic anhydride, citraconic anhydride, and itaconic
anhydride, and (ii) at least one unit of at least one monomer chosen
from allylic esters and methallylic esters optionally containing in
their chain at least one unit of at least one monomer chosen from
acrylamide, methacrylamide, α-olefin, acrylic esters, methacrylic
esters, acrylic acid, methacrylic acid, and vinylpyrrolidone;
wherein said anhydride functions of said (A) copolymers may be
monoesterified or monoamidated,
(B) copolymers comprising at least one unit of at least one monomer
chosen from acrylic acid and methacrylic acid, and at least unit of at
least one monoethylenic monomer chosen from ethylene, styrene,
vinyl esters, acrylic acid esters and methacrylic acid esters;
(C) copolymers comprising (i) at least one unit of at least one monomer
chosen from acrylic acid and methacrylic acid, (ii) at least one unit
of at least one monoethylenic monomer chosen from ethylene,
styrene, vinyl esters, acrylic acid esters and methacrylic acid
esters, and (iii) at least one unit of at least one monomer chosen
from vinyl acetate, N-alkyl (C3-C10) acrylamides, vinyllactams,
polyoxyalkylenated C6-C22 alkyl ethers, polyoxyalkylenated C6-C22
allyl ethers, polyoxyalkylenated C6-C22 methallyl ethers, non-
polyoxyalkylenated C6-C22 alkyl ethers, non-polyoxyalkylenated C6-
C22 allyl ethers, and non-polyoxyalkylenated C6-C22 methallyl
ethers.

Claims 1-19 stand rejected under 35 U.S.C. § 103 as obvious in view of Grollier.
We affirm.
Background
The specification discloses non-washing compositions useful as, e.g., hair
conditioners. See page 9, lines 9-12. The specification defines “non-washing” to mean
that the compositions “preferably contain less than 4% by weight of detergent
