Since the alkali-swelling of carboxylated latex particles (1-4) has been extensively studied by both industrial and academic scientists in the past, it has been well understood that their alkali-swelling increases with increasing acid content and hydrophilicity of backbone polymers and decreases with increasing [T.sub.g] of backbone and polymers and crosslink density of the whole polymers.
