In order to develop a kind of simulated stone like sesame effect multi-colorpaint to replace or partially replace stone paint. The effects of different kinds of protective gluesolution and their dosage，different kinds of cellulose and their dosage，different kinds of emulsion for continuous phases and basic color paint and their dosage on the state of sesameeffect multi-color paint and product performance were studied. The results showed that in theoptimal formula，the addition amount of CH31 was 0. 5%-0. 7%，the addition amount of HE10K was 0. 9%-1. 1%，the emulsion for basic color paint was 8027 and the addition amount was 20%-25%，and the emulsion for continuous phase was 8081 and the additionamount was 60%-65%. Under this process condition，the colored mottled stone dots produced were round and plump，with uniform size distribution，strong color penetration resistance，and excellent finished product performance. The simulated stone like sesame effect multi-colorpaint was superior to stone paint in terms of water resistance and stain resistance，and its decorative effect and texture could achieve a similar level as stone paint.
