| titleOfInvention | Method for preparing colored plastic materials using sorghum natural colors extract with improved stability |
| abstract | The present invention relates to a process for producing (a) a sorghum treating a natural pigment extract derived from a by-product of bicolor with a solution containing a metal salt to stabilize the pigment extract; And (b) mixing the stabilized coloring matter extract with a plastic molding material to produce a plastic molding. The present invention relates to a method for producing a plastic molding colored with an enhanced coloring matter extract, wherein the natural coloring matter extract Was chelated with a metal salt, and then, a plastic molding was produced by using the chelating agent. The color fastness was improved and color stability was excellent. Therefore, by using the plastic produced by this, a human-friendly and hygienic product containing a natural pigment can be developed. In particular, the present invention provides an optimal processing method for producing colored plastic injection molded articles using colored pigments extracted from silkworms. In order to improve low stability against sunlight, which is a problem of natural coloring matters, The finished product can be made more complete. |
