C.I. Pigment Yellow 13 was rosinated with abietic acid and the abietic
acid derivative, Staybelite, at up to 40% loading. The crude pigment,
recrystallised pigment and rosin coated pigment preparations were exa
mined by solid-state NMR spectroscopy and by powder X-ray diffraction.
The primary effect of the rosination procedure is to increase the cry
stalline order of the pigment. No evidence was found for any specific
pigment-rosin interactions, (C) 1997 Published by Elsevier Science Ltd
