prepared by using formulae such as No.1 and 2 that follow. A procedure
for preparing this type of resin emulsion is:
Step 1. Dissolve the resin in the solvent at room temperature and then
add the oleic acid. Best results are obtained when this resin solution
has a viscosity of 25 to 35 poises at room temperature. The cited
