In General Formula 1, R.sup.1 to R.sup.10, R.sup.15 and R.sup.16 represent a hydrogen atom, a hydroxy group, an aryl group, or an alkyl group having 1 to 3 carbon atoms; R.sup.11 and R.sup.12 represent an arylene group or an alkylene group having 1 to 3 carbon atoms; Y and Z represent a single bond or a divalent organic linking group; A represents a group having a pigment adsorption portion; B represents a group having a structure denoted by General Formula 2; l and n represent an integer of greater than or equal to 1; m represents an integer of greater than or equal to 0; and k represents an integer of greater than or equal to 1. ##STR00001##

The present invention provides a glass powder blend comprising glass powder and additives, wherein the additives comprise copper powder, and the copper powder accounts for 2-3 mass % based on the total amount of the glass powder blend in 100 mass %. The present invention also provides a glass powder paste and a photoelectric package. Due to the addition of copper powder to the glass powder, the melting point of the glass powder blend can be decreased, thereby lowering the temperature for melting the glass powder blend by using laser, and reducing the thermal stress generated during encapsulation.
