  • Patent number: 7750069
    Abstract: At least one resin component which is selected from a biodegradable resin and a plant-based resin, and a flame retardancy-imparting component are kneaded to obtain a resin composition having flame retardancy. This resin composition makes it possible to apply the environment-friendly resin such as the biodegradable resin and the plant-based resin, for example, polylactic acid and polybutylene succinate to exterior bodies of home appliances. Particularly, in the case where polylactic acid is used with the acetylacetonatoiron as the flame-retardant component, a resin composition having excellent flame retardancy can be provided as a non-halogen material.

  • Patent number: 6444146
    Abstract: An improved process for producing optical materials with minimized yellowing is described. The process is characterized by polymerizing/curing a composition for optical materials after adding a bluing agent. With the use of the bluing agent, the yellowing is minimized even when a large amount of an ultraviolet light absorber is used to improve a light resistance of the resultant optical material, thereby enabling the production of optical materials having a colorless and transparent appearance and excellent optical properties.
