Methods for forming images are disclosed. The images are formed by imaging and developing an imageable element comprising a layer of an imageable composition over a substrate. The imageable composition contains a polymeric binder, an acid activatable crosslinking agent, and an acid generator of the structure:
1
in which:
Y is hydrogen, halo, alkyl, diphenylamino, phenylthio, or (CH
2
)
k
SO
3
−
in which k is 1 to 4;
R
1
, R
2
, R
3
, and R
4
, are each independently hydrogen or SO
3
−
with the proviso that the anion has two to four SO
3
−
0 groups;
Z
1
and Z
2
are each independently a benzo group or a naphtho group;
Z
3
is two hydrogen atoms, a cyclohexene residue or a cyclopentene residue;
X1 and X2 are each independently S, O, NH, CH
2
, or CMe
2
;
Q
⊕
is an onium cation;
n is 1 to 4; and
m is 1 to 3, with the proviso that m is 1 when the anion has two SO
3
−
groups; m is 2 when the anion has three SO
3
−
groups; and m is 3 when the anion has four SO
3
