Make an M5G or MpO type containing e third or even a fourth element (in addi tion to the lead and ehroaliea). 3- Use the One or concept (core and. shell) to carry a useful organic materiel (ex. g., silicones) as the shell. k.

Pigment-polymer combinations primarily for use in electro-deposition, wherein the single charge on each particle would allow both pigment and vehicle to move at the same rate to the electrode] such combinations could be either latex-pigment or oil (or alkyd)-pigment. 18. Combine core and coating by a dry electrostatic process in which the two com ponents combine by neutralisation of their opposite electrical charges: such combinations could include different physical or chemical forms such as (l) a| solid core and an organic coating or (2) a solid core (ex. g., a chromate) en veloped fcy a v r " or dropJoc -etc. 19.
