First claim

The invention claimed is:

1. A coating composition comprising
a. polyvinyl chloride,
b. one or more compounds of the formula (I)

in which
R 1a and R 1b are independently of one another C 8 -alkyl

c. a mixture of diethylene glycol dibenzoate, triethylene glycol dibenzoate, and dipropylene glycol dibenzoate and
d. one or more compounds of the formula (IV),

wherein the proportion of the compound of the formula (I) is 5 to 150 phr, the proportion of the mixture of diethylene glycol dibenzoate, triethylene glycol dibenzoate, dipropylene glycol dibenzoate is 5 to 150 phr, and the proportion of one or more compounds of general formula (IV) is 0.1 to 10 phr and
with the proviso that the coating does not contain disononyl terephthalate.

2. The coating composition according to claim 1 , wherein a compound of the formula (I) is di(2-ethylhexyl) terephthalate.

3. The coating composition according to claim 1 , wherein the coating composition comprises one or more isocyanurates distinct from those of formula (IV).

4. The coating composition according to claim 1 , wherein the coating composition comprises one or more polymers distinct from polyvinyl chloride.

5. A process for producing a coating composition according to claim 1 , comprising the following steps:
a. suspending polyvinyl chloride in one or more compounds of formula (I),
b. adding one or more compounds of formula (IV) to the suspension obtained in step a.,

wherein one or more of the compounds having plasticizing properties, are a mixture of diethylene glycol dibenzoate, triethylene glycol dibenzoate, dipropylene and glycol dibenzoate and may be added in step a., or subsequent to step a. and prior to step b., in step b., or subsequent to step b., or at any desired times.

6. A process for coating fabric fibers or fabric, wherein one or more sides of the fabric fibers or of the fabric are contacted with the coating composition from claim 1 .

7. The process according to claim 6 , wherein the fabric is synthetic fabric.

8. An article comprising a fabric, wherein the fabric has been at least partially coated on one or more sides with the coating composition from claim 1 .

9. The coating composition according to claim 1 , wherein the proportion of the one or more compounds of the formula (IV) is 0.5 to 8 phr.

10. The coating composition according to claim 1 , wherein the proportion of the one or more compounds of the formula (IV) is 1 to 6 phr.

11. The coating composition according to claim 1 , wherein the proportion of one or more compounds of general formula (I) is 40 to 120 phr, the proportion of the one or more compounds having plasticizing properties is 20 to 100 phr and the proportion of the one or more compounds of the formula (IV) is 1 to 6 phr.

12. The coating composition according to claim 1 , which consists essentially of
a) polyvinyl chloride,
b) di(2-ethylhexyl) terephthalate,
c) a mixture of diethylene glycol dibenzoate, triethylene glycol dibenzoate, and dipropylene glycol dibenzoate,
d) one or more compounds of general formula (IV),
wherein the proportion of di(2-ethylhexyl) terephthalate is 20 to 100 phr, the proportion of the mixture of diethylene glycol dibenzoate, triethylene glycol dibenzoate, dipropylene and glycol dibenzoate is 20 to 100 phr, the total proportion of di(2-ethylhexyl) terephthalate and the mixture of diethylene glycol dibenzoate, triethylene glycol dibenzoate, and dipropylene glycol dibenzoate is 40 to 120 phr and the proportion of one or more compounds of general formula (IV) is 1 to 6 phr.

13. The coating composition according to claim 1 , wherein the compound of general formula (I) is selected from the group consisting of di(n-octyl) 1,2-terephthalate, di(isooctyl) 1,2-terephthalate, and di(2-ethylhexyl) terephthalate.
