PURPOSE:To obtain a solvent type treating agent for imparting water repellency and oil repellency, which has excellent durability and feeling to touch, by blending a fluorinated water and oil repellant with a specified carboxy-modified diorgano-polysiloxane softener. CONSTITUTION:A treating agent consists of a fluorinated water and oil repellant (1) and a carboxy-modified diorgano-polysiloxane softener (2) having at least two -Q-COOR6 and being represented by the formula. In the formula, R1, R2, R3, R4 and R5 are each a 1-20C hydrocarbon group; R6 is H or a monovalent hydrocarbon group; A1 and A2 are each a 1-20C monovalent hydrocarbon group or -Q-COOR6 (wherein Q is a bivalent hydrocarbon group); m is an integer; n is 0 or >=1; m+n>=10; m/(n+2)=5/1-500/1. Examples of the fluorinated repellant are homopolymers of a vinyl monomer having a 4-18C fluoroalkyl or fluoroalkenyl group, copolymers of said monomers and copolymers of said monomer with a vinyl monomer contg. no fluorine.
