Participants

Reaction Steps

2.5 parts of the powder dye described in Example 6 are dissolved in a mixture of 10 parts of a styrene/maleate hard resin having a softening point of 160°-175° C., 16 parts of a 60 percent strength solution of a condensate obtained from tert.-butylphenol, formaldehyde and salicylic acid in a molar ratio of 1:1.4:0.8 in a 9:1 mixture of ethanol and ethylglycol, and 74 parts of a 9:1 mixture of ethanol and a mixture of about 98% of 1-methoxypropan-2-ol and 2% of 2-methoxypropan-1-ol. This solution can be used, for example, to print paper or aluminum foil in a reddish-yellow hue (No. 4, Color Index Hue Indication Chart).
