Claims
- 1. A paper size comprising a self-emulsifiable mixture of 80 to 99 parts by weight of a cyclic dicarboxylic acid andydride having hydrophobic substitution and 1 to 20 parts by weight of an ethoxylated lanolin containing at least 15 moles ethylene oxide per mole lanolin wherein the cyclic dicarboxylic acid anhyride is represented by the formula: ##STR5## wherein R represents a dimethylene or trimethylene radical and wherein R.sup.1 is a hydrophobic group containing more than 4 carbon atoms which may be selected from the class consisting of alkyl, alkenyl, aralkyl, or aralkenyl groups. ##STR6##
- 2. The paper size mixture of claim 1 wherein the cyclic dicarboxylic acid anhydride is selected from the group consisting of: ##STR7## wherein R.sub.x is an alkyl radical containing at least 4 carbon atoms and R.sub.y is an alkyl radical containing at least 4 carbon atoms, and R.sub.x and R.sub.y are interchangeable; ##STR8## wherein R.sub.x is an alkyl radical containing at least 4 carbon atoms and R.sub.y is an alkyl radical containing at least 4 carbon atoms and R.sub.x and R.sub.y are interchangeable.
- 3. The paper size mixture of claim 1 wherein the ethoxylated lanolin contains 25 to 80 moles ethylene oxide per mole lanolin.
- 4. The paper size mixture of claim 1 wherein the ethoxylated lanolin is present in an amount less than 10 parts by weight of the mixture.
