Imageable multi-wall elastic sleeves

A tubular article comprising:

• a multi-wall extruded tube including an elastomeric outer wall having a first color and at least one elastomeric inner wall having a second color, said multi-wall extruded tube formed by co-extrusion to provide interlayer bonding including said elastomeric outer wall and said at least one elastomeric inner wall, said tubular article having visible indicia formed therein by removal of selected portions of said elastomeric outer wall using laser ablation to reveal said second color of said at least one elastomeric inner wall, said first color differing from said second color to provide high contrast of said indicia from said first color of said elastomeric outer wall, said tubular article being expandable for placement on a core member in an expanded condition wherein said interlayer bonding remains substantially unchanged.

A cold-shrink article comprising:

• a support core adapted to become a collapsed core;
• and
• a multi-wall elastic tube held in an expanded condition on said support core, said multi-wall elastic tube including an elastomeric outer wall having a first color and at least one elastomeric inner wall having a second color, said multi-wall elastic tube formed by co-extrusion to provide interlayer bonding including said elastomeric outer wall and said at least one elastomeric inner wall, said multi-wall elastic tube having visible indicia formed therein by removal of selected portions of said elastomeric outer wall using laser ablation to reveal said second color of said at least one elastomeric inner wall, said first color differing from said second color to provide high contrast of said indicia from said first color of said elastomeric outer wall, said multi-wall elastic tube in said expanded condition maintaining said interlayer bonding substantially unchanged, said multi-wall elastic tube shrinking as said support core becomes said collapsed core.
