to the above mother liquor 2 each organic solvent within the scope of the present invention was added to obtain the compositions having the concentration shown in table 8 and the mixture was mixed well to obtain sample liquors for evaluating coating properties the sample liquors were applied to glass substrates having transparent electrodes of ito as described examples 9 12 the coated substrates were dried and heated and the repellant properties and lack of uniformity were evaluated as described above the results are shown in table 8 table 8______________________________________ composition of organic solvents by weight lack ofexample compound name dmi repellant uniformity______________________________________24 n butyl lactate 60 33 6 no no25 pgb 50 44 no no26 mmb 50 44 no no27 pgb mmb 25 25 44 no no______________________________________ the same procedure as in examples 9 13 was repeated except that the compositions were applied by a printing machine and the drying temprature after coating was 80 u00b0 c to form a coating film on substrates and treat the substrates by heating the repellant properties and lack of uniformity were evaluated as described above the results are shown in table 9 table 9______________________________________ composition of organic solvents by weight lack of compound name dmi repellant uniformity______________________________________example pgb eca 30 50 15 no no28compar bc 80 15 no foundativeexample16______________________________________ in addition the composition of comparative example 16 precipitated a polymer in a freezer of 5 u00b0 c and the polymer was not easily dissolved on standing at room temperature on the other hand the composition of example 28 did not precipitate a polymer in a freezer at 40 u00b0 c in each of the examples nmp or dmi was used as component a not.
